The ST does work but not the way it would have during the war.Ducimus rig is really a tweaked SJ radar.

In reality it was a ranging only radar with a very limited FOV only a few degrees basically directly ahead so that a crewman could point the scope and the ST array attached to it at a location and get a range in return it was not tied into the PPI.ST had no "sweep" being a ranging radar not a search radar yuo would have already found your targets via other methods ST was just a highly accurate way to get an exact range(the SJ return could be off by many feet).The ST was really used for fire control and not searching.The St with the exception of the Barb was only installed on new Balao and Tench boats Fluckey got one mounted on the Barb because he was a god amongst men and he wanted to try it out.He did use it during one of his rocket attacks they used the ST and got the range from of a smoke stack of a paper factory.

On the Tench in TMO it performs like an SJ set with limited arc if I recall and its contacts did show up on the PPI.The other problem with ST in game is that it can also be detected which late war is a serious concern which forces you to use only the attack scope.In reality the ST was very narrow band making it very hard to detect especially for the Japanese.The SJ-1 was 10cm wavelength and the ST used 3cm wavelength the Japanese had very limited RWR capabilities during the war.

I think when Ubi was making the game they originally planned to include the ST but they either ran out of time or could not get it to work as a ranging set and therefore scrapped it.Ducimus added it into the Tench somehow if I recall it took him a lot of time and effort and he felt that it was not worth the trouble to make it an upgrade.

I have the same issues with the SV radar it does not function correctly in the game it behaves like an SJ set with better range that can spot both planes and surface contacts.SV did use the PPI though but because it behaves so unlike real SV I dont use it.SV was not installed on any boat until July of 45 anyway and too late to have seen any combat use.
